Energy-Efficient, Multi-Function 80-Watt Auto-Mixing Amplifier with Dual 70/100 V and 4 Ohms Outputs
MA6018/MA6008
Product Overview
EUROCOM MA6018/MA6008 professional mixer-
amplifiers offer extraordinary flexibility and ease-of-use
in an integrated rack-mountable system that is ideal
for commercial sound in facilities such as conference
rooms, houses of worship, restaurants, clubs, and similar
applications involving foreground music and paging.
Incorporating BEHRINGER’s exclusive DualDrive
technology, the MA6018/MA6008 is powered by
two independent mono amplifiers, one with a high-
impedance output that may be set to either 70 or 100 V,
and the other with a standard low-impedance output.
This versatile configuration enables easy installation of
hybrid multi-zone systems combining distributed and
low-impedance speakers, making the MA6018/MA6008 an
innovative solution for a broad range of environments.
The MA6018/MA6008 includes eight main channels for
balanced or unbalanced input from line-level sources
or microphones, either standard or phantom powered.
All channels accept input via both 5-pin Euroblock
connectors (with control and direct-out pins) and XLR/
TRS combination jacks. All main inputs are equipped
with a signal LED, gain trim, and high and low EQ. A set of
nine DIP switches on each channel assign the channel to
main and/or Zone 2 buses, set mic/line input, phantom
power on/off, set mute send/receive for channel muting,
and enable remote volume control, auto-mixing,
and chime activation for the channel. The level of each
channel in the main mix is set with individual front-panel
level controls.
Four additional auxiliary input channels, each with a
pair of RCA jacks that are summed internally to mono,
are provided for playback from external sources. A set of
four front-panel buttons determine which aux input is
currently sent to the main mix. Front panel controls are
also provided for the level and the EQ of the aux input.
A 4-pin Euroblock connector provides an additional
input (600 Ω, mic or line) for a telephone paging system.
MA6018/MA6008 telephone/paging functions, configured
via DIP switches, include assignable muting (signal,
switch, or contact closure activated), an assignable chime,
and assignment of any aux input to a Music on Hold (MOH)
bus. Controls are provided for the level of the paging send
to the main mix, the amount of ducking during pages,
the volume of the paging chime, and the level of the Music
on Hold feed.
MA6018/MA6008 outputs, all mono, include a single 4-pin
Euroblock connector for both high-and low-Z outputs to
loudspeakers as well as both Zone 2 and MOH outputs
combined onto a single 5-pin Euroblock connector.
The MOH out is fed from the main mix bus, while inputs to
the Zone 2 mix, which may be fed to an external recorder
or supplemental PA system, are assigned independently
of the main mix. Each output has a level control, and
neither is affected by master volume or EQ settings.
Additional MA6018/MA6008 connections include a 5-pin
Euroblock for remote control, switchable between the main
mix and the aux bus. Also on 5-pin Euroblock connectors
are Bridge In and Bridge Out, which allow multiple MA6000
series units to be bridged under the control of one master
unit. The master is determined by a setting on each unit’s
Main DIP switches, which also include settings for routing
the aux inputs, the aux bus, and the chime.
In addition, the MA6018/MA6008 front panel includes
a master level (main mix) knob—surrounded by an
indicator ring that glows yellow when the unit is powered
and flashes red at the onset of clipping—as well as high
and low EQ to optimize the main-mix sound for any
environment. Also included are a pair of LED meters that
indicate Main Mix and Zone 2 output levels.
MA6018/MA6008 operation is extraordinarily energy-
efficient thanks to transformerless Class-D amplifiers
that utilize switch-mode power supplies. The amplifiers
deliver 180 W (MA6018) or 80 W (MA6008) RMS into
low-Z loads of 4 Ω and high-Z outputs of 70 or 100 V.
A balance control adjusts the relative output of the two
amps, and a line-level effects send/receive, used to insert
external processing such as dynamics or EQ, is provided
using a single 5-pin Euroblock connector for both amps.
Each amplifier is protected with DC and thermal overload
protection, as well as by automatic limiting that prevents
overload, clipping, and distortion.
Combining powerful features and exceptional
configurability with a streamlined interface that is ideal for
non-technical users, EUROCOM MA6018/MA6008 mixer-
amplifiers provide outstanding value and functionality
for installed sound applications in a wide variety of
commercial installations.
